写了90%了，运行不了，一直报错

#include<stdio.h>

修改如下，供参考：

#include<stdio.h>
#include<string.h>
typedef struct {
    char name[10];
    long long qq;  //int 
    char xb;
    int  dj;
    char tx[10];
}gg;
int main() {
    gg a[20], b[20];
    int n, m, i, j, num;
    scanf("%d %d", &n, &m);
    for (i = 0; i < n; i++) {
        scanf("%s %lld %c %d %s", a[i].name, &a[i].qq, &a[i].xb, &a[i].dj, a[i].tx);
        //scanf("%s %d %s %d %s", a[i].name, &a[i].qq, &a[i].xb, &a[i].dj, a[i].tx);
    }
    for (i = 0; i < m; i++) {
        scanf("%lld %d", &b[i].qq, &num);
        for (j = 0; j < n; j++) {
            if (b[i].qq == a[j].qq) //if (strcmp(b[j].qq, a[i].qq) == 0)
                break;
        }
        switch (num) {
        case 1: {
            scanf("%s", b[i].name);  //scanf("%s", b[j].name);
            strcpy(a[j].name, b[i].name); //strcpy(b[j].name, a[i].name);
        }break;

        case 2: {
            scanf(" %c", &b[i].xb); // &b[j].xb
            a[j].xb = b[i].xb;     //b[j].xb = a[i].xb; 
        }break;
        case 3: {
            scanf("%d", &b[i].dj);  // &b[j].dj
            a[j].dj = b[i].dj;   //b[j].dj = a[i].dj;
        }break;
        case 4: {
            scanf("%s", b[i].tx); //b[j].tx
            strcpy(a[j].tx, b[i].tx); //strcpy(b[j].tx, a[i].tx);
        }break;
        }
    }
    for (i = 0; i < n; i++) {
        printf("[%d]:%s-%lld-%c-%d-%s\n", i + 1, a[i].name, a[i].qq, a[i].xb, a[i].dj, a[i].tx);
        // printf("[%d]:%s %d %s %d %s\n",i+1,a[i].name,&a[i].qq,a[i].xb,&a[i].dj,a[i].tx);
    }
    return 0;
}

是不是最后输出语句的问题，该这样试试：

#include<stdio.h>
#include<string.h>
typedef struct {
    char name[10];
    long long qq;  
    char xb;
    int  dj;
    char tx[10];
}gg;
int main() {
    gg a[20], b[20];
    int n, m, i, j, num;
    scanf("%d %d", &n, &m);
    for (i = 0; i < n; i++) {
        scanf("%s %lld %c %d %s", a[i].name, &a[i].qq, &a[i].xb, &a[i].dj, a[i].tx);
    }
    for (i = 0; i < m; i++) {
        scanf("%lld %d", &b[i].qq, &num);
        for (j = 0; j < n; j++) {
            if (b[i].qq == a[j].qq)
                break;
        }
        switch (num) {
        case 1: {
            scanf("%s", b[i].name);  
            strcpy(a[j].name, b[i].name);
        }break;

        case 2: {
            scanf(" %c", &b[i].xb); 
            a[j].xb = b[i].xb;    
        }break;
        case 3: {
            scanf("%d", &b[i].dj);
            a[j].dj = b[i].dj;  
        }break;
        case 4: {
            scanf("%s", b[i].tx); 
            strcpy(a[j].tx, b[i].tx); 
        }break;
        }
    }
    for (i = 0; i < n; i++) {
        printf(i == 0 ? "[%d]:%s-%lld-%c-%d-%s" : "\n[%d]:%s-%lld-%c-%d-%s", 
                        i + 1, a[i].name, a[i].qq, a[i].xb, a[i].dj, a[i].tx);
    }
    return 0;
}
